State The Law of Independent Assortment.

The Law of Independent Assortment states that when two or more characteristics are inherited, individual chromosomes assort independently during meiosis.

If a mutation introduces a new skin color in a lizard population, which might determine whether the frequency of the new allele will increase

Whether the mutation makes some lizards good for the environment

Gene changes include the independent movement of chromosomes during meiosis as well as

crossing over which occurs in prophase 1 of meiosis

Natural selection acts directly on

genes

Meiosis results in the formation of

haploid cells or diploid cells

How can a diagram of a population's age structure predict how it can grow?

it shows people at reproductive age and how many people are being born and the age people die

Why would it be impossible to have a pedigree halfly shaded

means you have the disease

In many kinds of organisms, what is the main cause of inheritable differences

mutations and crossing over in prophase 1, alignment of homologous chromosomes at metaphase 1, and orientation chromosomes at metaphase 2

What are some uses of a pedigree?`

shows if a trait is dominant or recessive, traces to see a disease throughout generations

As resources in a population become less available, what happens to population growth

you reach carrying capacity, and it doesn't change
